Money wasted on poor decision-making, jocularly

IDIOT TAX

Think of the informal term for the extra cost of a mistake—like speeding tickets or late fees—that some call a "fee for foolishness.

This clue plays on the idea of losing money due to bad choices, framed humorously as a "tax" you pay for being foolish. "Idiot tax" is a slang term for the extra costs or penalties that come from careless mistakes, like late fees or impulse buys. The word "jocularly" hints that the answer is a lighthearted phrase rather than a formal term.
